Uhlobo lokuqala luhlobo lwe-alloy ephansi, olumele ibanga le-UNS S32304 (23Cr-4Ni-0.1N). Insimbi ayinayo i-molybdenum, futhi inani le-PREN liyi-24-25. Ingasetshenziswa esikhundleni se-AISI304 noma i-316 mayelana nokumelana nokugqwala kwengcindezi.
Uhlobo lwesibili uhlobo lwe-alloy ephakathi, ibanga elimele i-UNS S31803 (22Cr-5Ni-3Mo-0.15N), inani le-PREN lingu-32-33, futhi ukumelana kwayo nokugqwala kuphakathi kwe-AISI 316L kanye ne-6% Mo + N austenitic stainless. insimbi. phakathi.
Uhlobo lwesithathu uhlobo lwengxubevange ephezulu, ngokuvamile equkethe u-25% Cr, futhi iqukethe i-molybdenum ne-nitrogen, kanti enye futhi iqukethe ithusi ne-tungsten. Ibanga elijwayelekile yi-UNSS32550 (25Cr-6Ni-3Mo-2Cu-0.2N), futhi inani le-PREN liyi-38-39 Ukumelana nokugqwala kwalolu hlobo lwensimbi kuphakeme kunalokho kwe-22% Cr duplex insimbi engagqwali.
Uhlobo lwesine uhlobo lwensimbi engagqwali eyi-duplex ephezulu, equkethe i-molybdenum ephezulu ne-nitrogen. Ibanga elijwayelekile yi-UNS S32750 (25Cr-7Ni-3.7Mo-0.3N), kanti amanye aqukethe ne-tungsten nethusi. Inani le-PREN likhulu kuno-40, elingasetshenziselwa izimo ezinzima Ezimaphakathi, ezinokumelana nokugqwala okuhle okuphelele kanye nezakhiwo zemishini, eziqhathaniswa nensimbi engagqwali ye-austenitic.
